For time-delay systems, the asymptotic behavior analysis of the critical imaginary roots w.r.t. the infinitely many critical delays is an open problem. In order to find a general solution, we will exploit the link between the asymptotic behavior of critical imaginary roots and the asymptotic behavior of frequency-sweeping curves, from a new analytic curve perspective. As a consequence, we will establish...
Question-oriented text retrieval, aka natural language-based text retrieval, has been widely used in software engineering. Earlier work has concluded that questions with the same keywords but different interrogatives (such as how, what) should result in different answers. But what is the difference? How to identify the right answers to a question? In this paper, we propose to investigate the "answer...
By employing composite right/left handed transmission line (CRLH-TL) structure, the proposed antenna for wireless universal serial bus (USB) dongle applications can provide two wide operation bands (746–960 and 2500–2690 MHz) to cover the LTE700/GSM850/900 and the LTE2500 operation. The proposed antenna utilizing a limited space of 12 × 28 × 5.8 mm3 consists of a folded monopole and a CRLH-TL structure...
Online social networking community is an important type of internet service. Large scale social network can be built upon the large quantities of user data kept by social networking community. We model the large scale social network on the live online community and evaluate the user relationship index from the model. We further use the user relationship index in analyzing the user relation data and...
As new strategic industry proposed by Premier Wen, environmental protection has once again to become the centre of attention. However, green product as the inevitable outcome of sustainable development of human beings, the evaluation study on it is of great significance. Based on green manufacturing and the conception of green product, this paper establishes product evaluation process of multilevel...
Better orderings of test cases can detect faults in less time with fewer resources, and thus make the debugging process earlier and accelerate software delivery. As a result, test case prioritization has become a hot topic in the research of regression testing. With the popularity of using the JUnit testing framework for developing Java software, researchers also paid attention to techniques for prioritizing...
With the development of the information and communication technology, the web has been very broadly integrated into various areas and units for education. Web courses, as an important learning resource, are evaluated through some norms.In this paper, we mainly discusses the similarity and difference among five evaluation norms of web courses and summarized for the late development of norms.
In this paper, a cooperative network coding scheme is proposed for a two-stage selective decode-and-forward relaying network with multiple source-destination pairs. In particular, based on employing Best-Select cooperation to perform relay selection, the selected best relay performs network coding on the correctly decoded information from all the sources, by transmitting a random linear combination...
An open source project typically maintains an open bug repository so that bug reports from all over the world can be gathered. When a new bug report is submitted to the repository, a person, called a triager, examines whether it is a duplicate of an existing bug report. If it is, the triager marks it as duplicate and the bug report is removed from consideration for further work. In the literature,...
